Siemens GFCI wiring

CAUTION
Electrical wiring and repairs can be dangerous, especially around water. There is a risk of shock or electrocution, which could result in serious injury or death. Hot tub electrical wiring or repairs should ONLY be done by a licensed electrician. Local code requirements for wiring vary and may differ from the educational examples on this web site. The local code regulations must be followed, with permits and inspections obtained. The electrician should read and follow the hot tub owner's manual and associated electrical component owner's manuals and  instructions. Regardless of who performs the work, be sure that power to the hot tub is turned OFF at the house service panel prior to inspections, wiring, or repairs. Improper wiring may damage equipment and void the manufacturer's warranty.
